Description

【0001】
【発明の属する技術分野】
本発明は基板搬送機構に係り、さらに詳しくは、無端搬送ベルトなどの無端搬送手段に実装基板を載置して次工程に搬送する際に確実に送り込むことができるようにした基板搬送機構に関する。
【0002】
【従来の技術】
実装基板を検査して良品と不良品とに仕分けする自動検査ラインにあって、検査終了後の実装基板は、通常、平行に配設される一対の無端搬送ベルト上に載置され、一枚ずつ次工程へと搬送され、例えば待機している多段式ラック内に一枚ずつ送り込むことができるようになっている。
【0003】
ところで、搬送される実装基板の中には、実装部品の種類とその実装位置とによって板面にかかる重量配分が異なり、例えば送り出し方向での先端部側が後端部側に比較して重くなっているものもある。このような重量配分となっている実装基板を無端搬送ベルトの側から次工程に送り出そうとするときは、次工程に先端部側が部分的に送り込まれた際、後端部側が無端搬送ベルトから浮き上がって搬送方向に送り込むための摩擦力が不足し、次工程の側に確実には送り込めなくなってしまう不都合があった。
【0004】
図3は、このような不都合を解消するために従来から採用されている実装基板の送り機構の一例を示す説明図である。
【0005】
同図によれば、実装基板の送り機構の全体は、前工程と次工程との間に配設される基板搬送手段2と、基板搬送手段2の側から実装基板Pを一枚ずつ次工程へと送り込む基板押込み手段6とを備え、装置本体1に対し各別に独立した機構のもとで配設されている。
【0006】
この場合、基板搬送手段2は、搬送方向との交差方向である横幅の設定が自在に装置本体1に配設されている一対の側板部3,3と、これらの側板部3,3の上端部に添設された案内部4,4と、これら案内部4,4を介して配設される無端搬送ベルト5,5とを備え、図示しないモータにより駆動される無端搬送ベルト5,5上に実装基板Pを載置することで前工程から次工程へと実装基板Pを搬送できるようになっている。
【0007】
また、基板押込み手段6は、次工程で待機している基板収納用ラック10が備える所定位置の棚部10aに対し無端搬送ベルト5,5上の実装基板Pを強制的に押し込むためのものであり、エアシリンダを利用して走行部8を進退制御する走行移動手段7と、前記走行部8に対し下方向での出没制御を自在に配設された押し込み作動片9とを備えて形成され、前記基板搬送手段2の上方に位置させて装置本体1に配設されている。
【0008】
【発明が解決しようとする課題】
ところで、図3に示す実装基板の送り機構によっても基板押込み手段6を作動させることにより重量配分を異にする実装基板Pであっても次工程へと確実に送り込むことはできる。
【0009】
しかし、基板押込み手段6は、図示しない作動杆を介して走行部8を進退制御するものであるため、実装基板Pが無端搬送ベルト5,5の終端側で滑動して次工程に送り込めなくなった場合に対処しようとするものである。このため、走行部8は、少なくとも実装基板Pの搬送方向での全長分を走行ストロークとして確保しておく必要があり、このような走行ストロークを得るためには、前記作動杆の長さも長いものが必要となり、結果的にコストの上昇を招いてしまう不都合があった。
【0010】
本発明は従来技術にみられた上記課題に鑑み、基板を次工程に強制的に送り込むための機構を簡素化してコストの低減を図ることができる基板搬送機構を提供することにその目的がある。
【0011】
【課題を解決するための手段】
本発明は上記目的を達成すべくなされたものであり、その構成上の特徴は、基板を載置して次工程への搬送を自在に平行配置される一対の無端搬送手段と、所定位置での搬送基板の有無状況を検出する基板検出センサと、該基板検出センサの検出信号に基づいて駆動制御される搬送支援手段とを少なくとも装置本体に備え、前記搬送支援手段は、昇降自在に駆動制御された作動杆を備えて無端搬送手段の終端側に位置させた作動部と、前記作動杆に支持されて従動する昇降部と、該昇降部の一側端面に回転自在に縦列配置された複数個の従動輪とからなる昇降ユニットを有し、該昇降ユニットは、基板検出センサの基板検出信号に基づき前記従動輪が搬送基板の搬送方向での一側縁部に接触するに至るまでの前記昇降部の降下制御と、前記基板検出センサの基板非検出信号に基づき前記昇降部の当初位置への上昇制御とを自在にして装置本体に配設したことにある。なお、前記搬送支援手段は、搬送基板の走行方向での送り込みを自在に進退する操作杆を有してなるプッシャーを前記昇降ユニットに組み合わせて構成し、前記プッシャーは、前記基板非検出信号に基づき進出制御される操作杆を介して次工程への搬送基板の強制的な送込みを自在にして装置本体に配設するものであってもよい。
【0012】
【発明の実施の形態】
図1は、本発明の実施の形態を具現化して例示する要部説明図であり、基板を載置して次工程への搬送を自在に平行配置される一対の無端搬送手段12,12と、所定位置での搬送基板35の有無状況を検出する基板検出センサ18と、該基板検出センサ18の検出信号に基づいて駆動制御される搬送支援手段21とを少なくとも装置本体11に備えてその全体が構成されている。
【0013】
この場合、前記無端搬送手段12のそれぞれは、例えば図示例のようにベルト車14を介して周回する無端搬送ベルト13により形成したり、図示は省略してあるがスプロケットを介して周回する無端搬送チェーンにより形成されているものなどを前記装置本体11の適宜の位置に配設することにより好適に用いることができる。
【0014】
また、前記基板検出センサ18は、搬送支援手段21に対し作動開始指令を送るべき位置、もしくは作動終了指令を送るべき位置における搬送基板35の有無状況を信号として検出するものであり、例えばフォトセンサなど、物体の有無を確実に電気信号として検出することができる適宜のセンサを用いて形成することができる。この場合、前記基板検出センサ18は、前記無端搬送手段12の搬送方向での終端12b側における装置本体11の適宜の位置、つまり、搬送基板35の先端部36が次工程の直前に達しているか否かと、搬送基板35の後端部38が次工程の直前を通過したか否かとを確実に検出できる装置本体11の所定位置に例えばブラケット19などの取付金具を介して配設するのが望ましい。
【0015】
一方、前記搬送支援手段21は、前記無端搬送手段12を介して移動する搬送基板35を次工程にて待機させてある例えば基板収納用ラックの棚板31上に確実に送り込むためのものであり、昇降自在に駆動制御された作動杆24を備えて無端搬送手段12の終端12b側に位置させた作動部23と、前記作動杆24に支持されて従動する昇降部25と、該昇降部25の一側端面26に縦列配置されて回転自在に軸支された複数個の従動輪27とからなる昇降ユニット22を少なくとも備えて構成されている。なお、昇降部25の一側端面26には、従動輪27の上方に位置させた庇部26aを設けておくのが安全性確保の観点からは望ましい。
【0016】
上記昇降ユニット22における作動部23は、エアシリンダのように空気等の流体により駆動制御されるものを好適に用いることができ、特に作動杆24が図示例のようにツインロッドタイプとなっているものを好適に用いることができる。また、前記作動部23は、前記無端搬送手段12の終端12b側に位置して、搬送基板35を確実に次工程の前記棚板31に送り込むことができる装置本体11の適宜の位置にねじ28等を用いて固着して配置するのが望ましい。
【0017】
また、昇降部25は、前記作動部23の作動杆24に下支えさせるなどして支持されるものであり、搬送基板35の規格サイズとの関係で定まる適宜大きさの金属材等を用いて形成されている。
【0018】
しかも、前記従動輪27は、搬送基板35の搬送方向での一側縁部37の上方に位置する関係におかれる該昇降部25の一側端面26に配設されており、したがって、これらの従動輪27も前記一側縁部37上に位置することになる。なお、これらの従動輪27は、例えばラジアルベアリング構造を備えて外周部が自在に回転するように支軸28を介して軸支されているものを好適に用いることができるほか、単に回転自在に軸支されているものであってもよい。また、前記従動輪27は、搬送基板35に対する接触時の衝撃を和らげたり、接触時の摩擦係数を高くする観点から、少なくともその接触周面にゴム材を配設するなどして予めクッション性を付与して形成しておくのが好ましい。
【0019】
このような構成からなる前記昇降ユニット22は、前記基板検出センサ18の基板検出信号に基づき前記従動輪27が搬送基板35の搬送方向での一側縁部37に接触するに至るまでの前記昇降部25の降下制御と、前記基板検出センサ18の基板非検出信号に基づき前記昇降部25の当初位置への上昇制御とを自在にして装置本体11に配設されている。
【0020】
また、前記搬送支援手段21は、搬送基板35の送り込みを自在に進退する操作杆を有してなるプッシャー(例えば走行ストロークをより短くした図3に示す基板押込み手段6のようなもの)を前記昇降ユニット22に付加して構成し、前記プッシャーを前記基板検出センサ18からの前記基板非検出信号に基づき進出する操作杆を介して次工程への搬送基板35の強制的な送込みを自在にして装置本体に配設するものであってもよい。
【0021】
本発明はこのようにして構成されているので、無端搬送手段12上の搬送基板35は図2の(イ)〜(ホ)に示すプロセスを経て次工程へと確実に送り込まれることになる。
【0022】
すなわち、同図の(イ)に示すように、無端搬送手段12の始端12a側に載置された搬送基板35は、無端搬送手段12の動きとともにその終端12b方向に向かって同図の(ロ)に示すように移動する。
【0023】
搬送基板35は、やがてその先端部36が基板検出センサ18上に到達し、基板検出センサ18から昇降ユニット22に対し基板検出信号が発せられ、作動部23の作動杆24が所定位置にまで降下する結果、昇降部25も同様にして降下し、その一側端面26に配設されている従動輪27が同図の(ハ)に示すように搬送基板35の一側縁部37と接触するに至る。
【0024】
このとき、搬送基板35は、従動回転する従動輪27に押え込まれながら無端搬送手段12の動きとともに終端12b方向へと移動するので、例えば搬送基板35の先端部36側に重量が偏って重くなっている場合であっても、同図の(ニ)に示すように次工程に位置している棚板31方向へと円滑に送り出すことができる。
【0025】
しかも、同図の(ホ)に示すように搬送基板35の後端部38が基板検出センサ18上を通過すると、基板検出センサ18から昇降ユニット22に対し基板非検出信号が発せられ、作動部23の作動杆24が当初位置にまで上昇する結果、昇降部25も同様にして上昇し、同図の(イ)の状態へと復帰し、以後、同様な動作を繰り返し行う。
【0026】
なお、前記昇降ユニット22と、搬送基板35の送り込みを自在に進退する操作杆を有して無端搬送手段12の終端12b近傍に配設されたプッシャーとで前記搬送支援手段21が構成されている場合には、前記プッシャーを前記基板検出センサ18からの前記基板非検出信号に基づき進出する操作杆を介して次工程へと比較的短い走行ストロークのもとで搬送基板35をより確実に送り込むことができる。
【0027】
【発明の効果】
以上述べたように本発明によれば、昇降ユニットを基板検出センサからの信号により昇降制御することができるので、昇降部が備える従動輪を搬送基板に接触させながら単に搬送案内することにより、重量配分に偏りがある搬送基板であっても簡易な構造の機構のもとで次工程へと確実に送り込むことができる。
【0028】
また、前記昇降ユニットと、搬送基板の送り込みを自在に進退する操作杆を有して無端搬送手段の終端近傍に配設されたプッシャーとで前記搬送支援手段が構成されている場合には、昇降ユニットの支援のもとで走行ストロークを比較的短くしたプッシャーを用いることができるので、コストを比較的低く抑えるなかで、搬送基板を次工程により確実に送り込むことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a substrate transport mechanism, and more particularly to a substrate transport mechanism that can be securely fed when a mounting substrate is placed on an endless transport means such as an endless transport belt and transported to the next process.
[0002]
[Prior art]
In an automatic inspection line that inspects the mounting board and sorts it into non-defective products and defective products, the mounting board after the inspection is usually placed on a pair of endless conveyor belts arranged in parallel, one sheet It is conveyed to the next process one by one and can be fed, for example, one by one into a waiting multi-stage rack.
[0003]
By the way, in the mounting board to be transported, the weight distribution applied to the plate surface differs depending on the type of mounting component and its mounting position. For example, the front end side in the feeding direction is heavier than the rear end side. Some are. When trying to send the mounting board with such weight distribution from the endless transport belt side to the next process, when the front end part is partially sent to the next process, the rear end side is the endless transport belt. There is a problem that the frictional force for lifting from the side and feeding in the conveying direction is insufficient, and it is not possible to reliably feed to the next process side.
[0004]
FIG. 3 is an explanatory view showing an example of a mounting board feeding mechanism that has been conventionally employed in order to eliminate such inconvenience.
[0005]
According to the figure, the entire mounting substrate feed mechanism is composed of the substrate transport means 2 disposed between the previous process and the next process, and the mounting substrate P one by one from the substrate transport means 2 side. And a substrate pushing means 6 for feeding into the apparatus main body 1.
[0006]
In this case, the substrate transfer means 2 includes a pair of side plate portions 3 and 3 disposed in the apparatus main body 1 so that a lateral width which is a direction intersecting the transfer direction can be freely set, and upper ends of these side plate portions 3 and 3. On the endless conveyor belts 5 and 5 that are driven by a motor (not shown). By mounting the mounting board P, the mounting board P can be transferred from the previous process to the next process.
[0007]
The board pushing means 6 is for forcibly pushing the mounting board P on the endless transport belts 5 and 5 into a shelf 10a at a predetermined position provided in the board storage rack 10 waiting in the next process. A travel moving means 7 for controlling the travel portion 8 to move back and forth using an air cylinder, and a push-in operating piece 9 that is freely arranged to move in and out in the downward direction with respect to the travel portion 8. The apparatus main body 1 is disposed above the substrate transfer means 2.
[0008]
[Problems to be solved by the invention]
By the way, even the mounting substrate P having a different weight distribution by operating the substrate pushing means 6 by the mounting substrate feeding mechanism shown in FIG. 3 can be reliably fed to the next process.
[0009]
However, since the board pushing means 6 controls the traveling portion 8 to move back and forth through an operating rod (not shown), the mounting board P cannot slide to the next process because it slides on the terminal end side of the endless conveyor belts 5 and 5. If you are trying to deal with. For this reason, it is necessary for the traveling unit 8 to ensure at least the entire length of the mounting substrate P in the transport direction as a traveling stroke. In order to obtain such a traveling stroke, the length of the operating rod is long. As a result, there is a disadvantage that the cost increases.
[0010]
SUMMARY OF THE INVENTION In view of the above problems found in the prior art, the present invention has its object to provide a substrate transport mechanism capable of simplifying a mechanism for forcibly feeding a substrate to the next process and reducing the cost. .
[0011]
[Means for Solving the Problems]
The present invention has been made to achieve the above-described object, and has the structural features of a pair of endless transfer means on which a substrate is placed and freely transferred in parallel to the next process, and a predetermined position. A substrate detection sensor for detecting the presence / absence of the transfer substrate and a transfer support unit that is driven and controlled based on a detection signal of the substrate detection sensor are provided at least in the apparatus main body, and the transfer support unit is driven and controlled to freely move up and down. An actuating portion provided on the end side of the endless transport means, a lifting portion supported and driven by the actuating rod, and a plurality of columns arranged rotatably on one end face of the lifting portion. The lifting unit is composed of a plurality of driven wheels, and the lifting unit is based on the substrate detection signal of the substrate detection sensor until the driven wheel comes into contact with one side edge in the transport direction of the transport substrate. The lowering control of the lifting part In that disposed on to the apparatus main body to freely and increase control of the initial position of the elevating unit based on the substrate of the sensor non-detection signal. The transfer support means is configured by combining a pusher having an operating rod for freely moving the transfer substrate in the running direction with the lifting unit, and the pusher is based on the substrate non-detection signal. It may be arranged in the apparatus main body so that the forcible feeding of the transfer substrate to the next process can be freely performed via an operation rod whose advance is controlled.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an explanatory view of a main part that embodies and exemplifies an embodiment of the present invention, and includes a pair of endless transfer means 12 and 12 on which a substrate is placed and freely transferred in parallel to the next process. The apparatus main body 11 is provided with at least a substrate detection sensor 18 for detecting the presence / absence of the transfer substrate 35 at a predetermined position and a transfer support means 21 that is driven and controlled based on a detection signal of the substrate detection sensor 18. Is configured.
[0013]
In this case, each of the endless transport means 12 is formed by, for example, an endless transport belt 13 that circulates through a belt wheel 14 as shown in the drawing, or is endless transport that circulates through a sprocket, although not shown. What is formed of a chain can be suitably used by disposing it at an appropriate position of the apparatus main body 11.
[0014]
The substrate detection sensor 18 detects the presence / absence of the transport substrate 35 at a position where an operation start command should be sent to the transport support means 21 or a position where an operation end command should be sent. For example, an appropriate sensor that can reliably detect the presence or absence of an object as an electrical signal can be used. In this case, the substrate detection sensor 18 has an appropriate position of the apparatus main body 11 on the end 12b side in the transport direction of the endless transport means 12, that is, the front end portion 36 of the transport substrate 35 has reached just before the next process. It is desirable to dispose, for example, via a mounting bracket such as a bracket 19 at a predetermined position of the apparatus main body 11 that can reliably detect whether or not the rear end portion 38 of the transport substrate 35 has passed immediately before the next process. .
[0015]
On the other hand, the transport support means 21 is for surely feeding the transport substrate 35 moving via the endless transport means 12 onto the shelf plate 31 of the substrate storage rack that is waiting in the next process, for example. An actuating portion 24 that is controlled to be movable up and down and is positioned on the end 12b side of the endless conveying means 12, an elevating portion 25 supported by the actuating rod 24 and driven, and the elevating portion 25 The elevating unit 22 is composed of a plurality of driven wheels 27 that are arranged in tandem on one side end face 26 and rotatably supported. In addition, it is desirable from the viewpoint of ensuring safety to provide the collar part 26a located above the driven wheel 27 on the one end face 26 of the elevating part 25.
[0016]
The operating unit 23 in the lifting unit 22 can be suitably used that is driven and controlled by a fluid such as air, such as an air cylinder. In particular, the operating rod 24 is a twin rod type as shown in the drawing. A thing can be used suitably. The actuating portion 23 is positioned on the end 12b side of the endless conveying means 12, and the screw 28 is placed at an appropriate position on the apparatus main body 11 where the conveying substrate 35 can be reliably fed into the shelf 31 in the next process. It is desirable to fix and arrange using, for example.
[0017]
The elevating unit 25 is supported by being supported by the operating rod 24 of the operating unit 23, and is formed using a metal material having an appropriate size determined in relation to the standard size of the transport substrate 35. Has been.
[0018]
Moreover, the driven wheel 27 is disposed on the one end face 26 of the elevating part 25 which is positioned above the one side edge 37 in the transport direction of the transport substrate 35. The driven wheel 27 is also located on the one side edge 37. These driven wheels 27 can be suitably used, for example, having a radial bearing structure and being pivotally supported via a support shaft 28 so that the outer peripheral portion can freely rotate. It may be pivotally supported. In addition, the driven wheel 27 has a cushioning property in advance by, for example, disposing a rubber material on at least the contact peripheral surface from the viewpoint of reducing the impact at the time of contact with the transport substrate 35 or increasing the friction coefficient at the time of contact. It is preferable to form by giving.
[0019]
The elevating unit 22 having such a configuration elevates the elevating unit 22 until the driven wheel 27 comes into contact with one side edge 37 in the conveying direction of the conveying substrate 35 based on the substrate detection signal of the substrate detecting sensor 18. The apparatus body 11 is disposed in the apparatus main body 11 so as to freely control the lowering of the part 25 and to control the raising / lowering part 25 to the initial position based on the substrate non-detection signal of the substrate detection sensor 18.
[0020]
Further, the conveyance support means 21 is provided with a pusher (for example, the substrate pushing means 6 shown in FIG. 3 having a shorter travel stroke) having an operating rod for freely moving the conveyance substrate 35 forward and backward. The pusher is configured to be added to the elevating unit 22 so that the pusher can be forcibly fed into the next process via an operation rod that advances based on the substrate non-detection signal from the substrate detection sensor 18. It may be arranged in the apparatus main body.
[0021]
Since the present invention is configured as described above, the transfer substrate 35 on the endless transfer means 12 is surely sent to the next step through the processes shown in FIGS.
[0022]
That is, as shown in FIG. 6A, the transfer substrate 35 placed on the start end 12a side of the endless transfer means 12 moves toward the end 12b along with the movement of the endless transfer means 12. ) Move as shown.
[0023]
The transport substrate 35 eventually reaches its top end 36 on the substrate detection sensor 18, a substrate detection signal is issued from the substrate detection sensor 18 to the lifting unit 22, and the operating rod 24 of the operating unit 23 is lowered to a predetermined position. As a result, the elevating part 25 is similarly lowered, and the driven wheel 27 disposed on the one end face 26 comes into contact with the one side edge 37 of the transport substrate 35 as shown in FIG. To.
[0024]
At this time, the transport substrate 35 moves in the direction of the terminal end 12b along with the movement of the endless transport means 12 while being held by the driven wheel 27 that is driven and rotated, so that the weight is biased toward the front end portion 36 of the transport substrate 35, for example. Even if it is, it can be smoothly sent out toward the shelf 31 located in the next step as shown in FIG.
[0025]
In addition, when the rear end portion 38 of the transport substrate 35 passes over the substrate detection sensor 18 as shown in FIG. 5E, a substrate non-detection signal is issued from the substrate detection sensor 18 to the lifting unit 22, and the operating portion. As a result, the lifting / lowering unit 25 also rises in the same manner and returns to the state of (a) in the figure, and thereafter the same operation is repeated.
[0026]
The transport support means 21 is composed of the lifting unit 22 and a pusher disposed in the vicinity of the terminal end 12b of the endless transport means 12 with an operating rod for freely moving the transport substrate 35 forward and backward. In this case, the transport substrate 35 is more reliably fed to the next process through the operation rod that advances based on the substrate non-detection signal from the substrate detection sensor 18 under a relatively short travel stroke. Can do.
[0027]
【The invention's effect】
As described above, according to the present invention, the lifting unit can be controlled to move up and down by a signal from the substrate detection sensor. Even a transport substrate with a biased distribution can be reliably sent to the next process under a mechanism with a simple structure.
[0028]
Further, when the transport support means is constituted by the lifting unit and a pusher provided with an operating rod for freely moving the transport substrate forward and backward and disposed near the end of the endless transport means, Since a pusher having a relatively short travel stroke can be used with the support of the unit, the transport substrate can be reliably fed in the next process while keeping the cost relatively low.
